Overview

tRNA and tRF/tiRNA layers in metabolic regulation

tRFs and tiRNAs, generated through precise biogenesis processes from tRNA, alter embryonic transcriptional cascades as paternal epigenetic factors in intergenerational inheritance of metabolic disorders [1].

Background

tRNA and tRF/tiRNA in metabolism and inheritance

tRFs and tiRNAs, generated through precise biogenesis processes from tRNA, perform many biological functions as small noncoding RNAs (Fig. 1). They alter embryonic transcriptional cascades as paternal epigenetic factors in intergenerational inheritance of metabolic disorders [1].

Defects in tRNA modifications and modification enzymes are linked with human diseases such as cancers, diabetes, neurological syndromes, cardiac conditions, and mitochondrial-linked disorders [2]. tRNA modification profiles are key to establishing the link with the disease and tRNA molecular functioning.

tRNA and tRF&tiRNA populations are highly enriched in biofluids, much more so than microRNAs [3-4], supporting metabolic biomarker studies in serum and plasma.

Sample Requirements

Official Arraystar sample submission requirements for metabolic research projects

RNA Amount & Quality

  • Total RNA input: > 1 µg for tRF&tiRNA-seq, > 2 µg for tRNA-seq, 10*–15 µg for LC-MS, and > 5 µg for PCR array projects (official recommended minimums, including sample QC). Supply twice the recommended minimum to avoid project delays.
  • Purification: TRIzol / RNA precipitation or an RNA isolation kit. Because tRNA and tRF/tiRNA are < 200 nt, use a kit specified to retain small RNAs (e.g. Qiagen miRNeasy).
  • Concentration: > 20 ng/µL by Nanodrop; OD260/280 ~2.0 (acceptable 1.7–2.1); OD260/230 > 1.8.
  • Integrity: sharp 18S/28S rRNA bands by gel, or RIN > 7.0 by Bioanalyzer (serum/plasma/exosome/FFPE RNA exempt).
  • DNase treatment: required for qPCR projects; optional for sequencing and LC-MS.

Shipping Instructions

  • Ship RNA in nuclease-free water (> 20 ng/µL), freeze-dried, or in ethanol; store at −80 °C or in liquid nitrogen.
  • Use nuclease-free certified, screw-cap 1.5 mL microtubes; seal caps with Parafilm; place tubes in a plastic bag.
  • Use 10 kg dry ice as refrigerant; include a signed Project Form and the sample list.

FAQ

Common questions about metabolic syndrome & epigenetic inheritance studies

How are tRFs/tiRNAs linked to epigenetic inheritance?
tRFs and tiRNAs alter embryonic transcriptional cascades as paternal epigenetic factors in intergenerational inheritance of metabolic disorders. tRF&tiRNA-seq profiles these tRNA-derived small RNAs in sperm and other relevant samples to study their inheritance-related functions and mechanisms in metabolic programming across generations and tissues.
Which services profile tRNA modifications in metabolic disease?
LC-MS based tRNA modification analysis quantifies 55 nucleoside modifications globally and characterizes the modification profile of tRNAs, which is key to establishing the link between tRNA modifications and diseases such as diabetes and metabolic conditions, complementing expression profiling by sequencing and arrays.
What is the minimum amount of RNA required?
Recommended minimums are more than 1 µg of total RNA for tRF&tiRNA-seq, more than 2 µg for tRNA-seq, 10–15 µg for LC-MS analysis, and more than 5 µg for PCR array projects — official Arraystar recommended minimums for the entire experiment in a single attempt, including sample QC.
Can biofluid samples be used?
Yes. tRNA and tRF&tiRNA populations are highly enriched in biofluids, much more so than microRNAs. Serum, plasma, and other biofluid samples can be profiled, following the official collection guidance; fragmented biofluid RNA is not checked for integrity, supporting metabolic biomarker studies.
What bioinformatics analyses are included?
Sequencing projects include differential expression with detailed annotation and subtype analysis; LC-MS projects include raw and normalized peak data, Total Ion Current chromatograms, and differential modification among samples; array projects include ready-to-analyze data with quality controls and analysis tools for interpretation.
Can the solution be combined with other Arraystar services?
Yes. tRNA modification sequencing (m1A, m3C, m1G, m2,2G; m7G; m3C), tRNA Charging Seq, and other services can be added for integrated tRNA studies within Arraystar's research portfolio, connecting metabolism research with epitranscriptomic regulation and inheritance biology in the same framework and study cohort.
